MuSICA, Daidalus, ACAS Xu, MIDCAS, ODREA… there are multiple projects building a Detect and Avoid (DAA) system, yet it is not possible to compare they performances in different operational conditions. Though evaluating a whole DAA system may appear as a daunting task, splitting the system in two: a Collision Avoidance (CA) and Remain Well Clear (RWC) functions allows simpler evaluations for cases where only one of these is needed.

As a matter of fact, the RPAS Chair is proposing to extend a current SESAR2020 project to create a much needed open Benchmark for Collision Avoidance Systems: BCAS (Bécasse, in French, like the bird). The goal is to extend the current work, performed in the SESAR2020 PJ11-A2 project on evaluating ACAS Xu with fast time simulations, to evaluate other collision avoidance algorithms.

Now the difficult part is to choose carefully the scope of the simulator: which airspaces, which types of operations, which types of RPAS, which evaluation metrics ? In order to answer these questions, a researcher from the Chair presented the BCAS project to the JARUS Work Group 4 (Detect & Avoid) and 6 (Safety & Risk Management) joint meeting. It allowed gathering valuable informations about ongoing projects in similar topics, obstacles to overcome, and how to reach a trustworthy benchmark.

The light shed by the JARUS members on this project allowed coming one step closer to the definition of what BCAS needs to do.
